Hi James,
You should read the site rules and guidelines for posting videos and also for posting items for sale. It's all covered here in the site rules:
http://fotmd.com/forums/forum/faq-site-rules-please-read/22/faq-member-guidelines-please-read
I'm assuming you are referring to marketing/selling dulcimers. There are only two locations you can sell or market items here in FOTMD- either in the For Sale forum (while following its guidelines), or by purchasing a slideshow Ad in the Main Page sponsor showcase. You cannot market a dulcimer for sale through posting a video here. Selling and marketing is confined to the For Sale Forum and to the Ad Slideshow. Hope this answers your question.
